Vietnamese input,
everywhere you type.

A Vietnamese input method that uses the backspace technique instead of a composition window — so Telex works in browser URL bars, terminals, editors, and every other app. Fast, lightweight, and private.

What makes NovaKey different

04 / Highlights

Works everywhere

A global CGEvent tap sends backspaces and Unicode instead of using IMKit's marked text, so it just works in Chrome URL bars, Terminal, VS Code, and Spotlight.

Smart tone placement

Modern Vietnamese orthographic rules place tones correctly — hoang + f lands the huyền on the a, not the o.

English-word protection

Telex transforms are gated on syllable validity, so class, know, and add stay literal instead of turning into Vietnamese.

Double-press escape

Typing a Telex key twice trusts the second press unconditionally — disst becomes dist, noww becomes now, corrrection becomes correction.
